[NETFILTER]: nf_queue: move list_head/skb/id to struct nf_info
Move common fields for queue management to struct nf_info and rename it
to struct nf_queue_entry. The avoids one allocation/free per packet and
simplifies the code a bit.
Alternatively we could add some private room at the tail, but since
all current users use identical structs this seems easier.
